1. Technical Principles and Site Characteristics

Reinforced steel truss floor decking is a composite structure where the reinforcing steel bars in the floor slab are prefabricated into truss shapes in a factory and welded to profiled steel sheets.

The dense mesh of reinforcing steel trusses in the image is the finished product laid on-site after prefabrication in the factory. The profiled steel sheets below serve as formwork during the construction phase, while the reinforcing steel bars above directly contribute to the floor slab's load-bearing capacity.

This design eliminates the need for complex on-site rebar tying, significantly reducing the workload of high-altitude operations.

2. Core Advantages for Xiong'an New Area

As a "millennial project," Xiong'an New Area has strict requirements for green, efficient, and high-quality construction. Reinforced steel truss floor decking perfectly meets these goals:

High Construction Efficiency: Factory prefabrication and direct on-site installation save approximately 60% of the time required for traditional formwork erection and rebar tying, facilitating rapid project completion and matching the pace of large-scale, rapid construction in the new area.

Superior Structural Performance: The truss reinforcement works in tandem with concrete, significantly improving the floor slab's load-bearing capacity and crack resistance, meeting the high-standard durability requirements of Xiong'an New Area.

Green and Environmentally Friendly: Profiled steel sheets can replace traditional wooden formwork, reducing timber consumption; construction waste is minimized, aligning with the new area's "green and low-carbon" construction philosophy.

Flexible Space Utilization: The flat bottom of the floor decking facilitates subsequent electromechanical pipeline installation, making it particularly suitable for large-span public buildings or industrial structures like the one pictured.

3. On-site Application Scenarios

From the construction stages shown in the images: Currently, the floor decking has been laid and is ready for concrete pouring. Multiple tower cranes are working collaboratively on-site, demonstrating the efficient organizational model of "three-dimensional, cross-sectional, and continuous construction" in the Xiong'an project.

This technology is particularly suitable for large-span, large-space building types commonly found in Xiong'an New Area, such as multi-story factories, industrial parks, and public buildings, effectively shortening the construction period and ensuring structural safety.
